positio'iie' .iliimediatel aboye lie Thegag hal 8 is provided with toothed rack 15 adapted to fitthe threads 16 of a worm revolubly mounted upon a spin-' dle 17 journaled in suitable bearings 18 formed in the bracket on the arm 12. The bracket 14 hassecured thereto a follower 19 which fits over a longitudinal track 20 on the gage bar 8. The arrangement of the follower 19 on the bracket 14 provides a groove in the bracket in which the track 20 is adapted to fit. By this construction the weight of the outer end of the arm causes one wall of the groove tobear against the point 20 on the track and the opposite wall of the groove-to bear against the point 20 on the track, whereby a proper relation of the parts is maintained irrespective of the fit ofthe track 20 in the groove formed on'the bracket. To one end of the follower 19 is secured the memberB-l (Fig. VII) which is provided with a toe 22 which fits a 1ong1- tudinal recess in one of the walls of the groove 20. The toe of thisfollower il ting.

1n the longitudinal groove prevents the bodily removal of the frame carrying the worm from the gage part at the same time;

it permits the raising of the forward en of the frame which discngages the Worm from therack; therefore the worm 16 may with rapidity be moved to any position on the gage bar by lifting the sliding arm to ,disengage the worm from the threaded rack and then moving the sliding arm to or near the desired position. At the top near the front edge, the gage bar is graduated to indicate pleas, and there are preferably fifty pica divisions to the left of the upstanding shoulder 23 (Fig. II) the gage being sufficiently longer to permit the micrometer gage to rest on the bar at the left of the fiftieth division. Readings are taken at the right end of the bracket, it being noted that the width of the straight edge 13 equals that of the upstanding shoulder 23. A zone 2a atone extremity of the worm is graduated and marked toindicate points; the entire circumference of the zone or the distance around the same being divided into twelve points or one pica. The teeth of the gage ar 8 which the Worm engages and the threads of .the worm itself are so cut that their pitchbears a definite relation to the the . the worm will move the bar a distance equal ,rangement 1 iustment o ength of the material sawed may be regulatedto a point, or one-twelfth of a pica.

to one point. This construction and arpermits of fine and accurate adthe sliding armwhereby the 9 When it is desired to cut material of considerable length, the attachment shown in Fig. XIII may be used. In this attachment a graduated slide rod 25 is attached to a member similar to the bracket of the sliding arm 12 and having similar parts associate with the ga e bar. The slide rod extends longitudinal y of the main gage 8 on which it is slidably mounted, and carries theslidable arm 26 which is provided with a straight edge at right angles to the slide rod. In this case, the rod is marked at points of 50 and 100 picas from the right end of the member on the main gage and thus the arm may be set to add these numbers of icas to any number of the picas, or picas an points, indicated on the main and micrometer gages.

Another feature of my invention is the provision of means for holding the material in place upon theinovable table as the latter is movedforwardly to bring the material to be acted on by the saw into operative relation therewith. In using sawing and trimming apparatus of this class particularly provements provide means for effectively.

performing these functions.

Mounted on the sliding table 2 in suitable proximity to its edge 27 is an upwardly projecting casing 28, which in position, cants toward the table forming an oblique angle with the plane thereof. The lower extremity of this casing is beveled to allow it to rest flat upon the table when its body portion projects upwardly at an inclination as just- I explained. The casing 28 is provided with a dependi-ng pin or stem 29 whose axis extends at right angles to the plane of the table. This stem 29 enters a circular recess formed in .the sliding table 2 and a small round bar 30 is secured in position in the recess in the rear.

The casing 28 is provided with a stem 29 which is formed integrally on a plug 31 held in the bottom of the casing by a pin or key 32, making the casing and plug substantially integral, so far as the operation is concerned. This stem 20 has formed therein a tiansv'erse groove 33 and has one side flattened as at 33. In attaching the work-holding device to the table the device is swung at an angle to the right about 90 degrees from the position shown in the drawings and the stem 29 is inserted in the circular recast or opening formed in the table to receive the same, the flattened portion 33 of the stenl permitting the stem to pass the pin 30. When the Workholding device. is

swung into normal position the groove 33 will engage the pin 30 and the worleholding device will be heldin position on the table,

In removing the work-holding device from the table it is swung to-Qhe right about 90 degrees or until the flattened orstraight edge portion 33 is opposite the pin 33,,when, it will be seen, the stem 29 may be readily disengaged from the 'pin 33.

Above the plug 31 in the casing 28 is 10- catedammrable piston 34, which fits closely within the casing and is connected with a piston rod 35 surrounded by a coiled spring 36, one extremity of which spring nets on the piston 34 while the other extremity en-.

- gages the upper end of the casing The piston rod 35 extends upwardly through an opening in the top of the casing and has, its upper-portion bifurcated to form two arms 37, adapted to receive one extremity of a slide 38 provided with an opening to receive the pin 39, passed through registering apertures formed in the parts 37 and the ..reai"extremity of the slide arm 38. This arm 38 consists on a bar which extends for wardly from they casing 28 and has slidebly mounted thereonlt he retaining device 4O,

consisting 'offthefupper member 41 provided with ajg'roove fitting thetop of the arm 38,

- is pivotedfat 43, to the upper member and and the'lowe'r grooved member 42, which P id QWithYQ depending. projection or jaw 44, At theforward extremity of the..- npper' member is provided a part ip/with an opening throughwhichthe arm may pass and a handle Miter-shifting the device along the arnr'38', At 'the rear. at; 457;, the, groove F in the lower. mense is de'peli' and slopes downwardly, The lower edge of the mem- .ber 42 is providedwith a strip 48 of; suitable yielding. material, as rubber,wh ereby stock or'materiallto be operated on is not injured by downward pressure of the device.

With the above construction in shifting the retaining device the lower member falls away from'the slide rods so that the whole may be moved on the rod with a minimumof. frictional resistance. I

Conveniently mounted pivotally on the gage bar 8,is a spring operated latch 49, provided with an arm 50arrtmged to, engage the retaining device after the same has been brought into operative relation with respect to-the material to be operated on, to thereby hold that device down on the material.

' I n order to'hold material which it is de sired to split-or trimlongitudinally, 1 prov ide clamping means which may be readily attached to the straight edgefof the, arm 12. On the side at the front ofthe straight edge a small plate 51 having a counter-sunk open- 'b g-52 .th'eretln'ougl'i, below its center and its serrated front edge 53 fitson the eccentric head 54 of a small shat't fifi-which journals in the boss 56 on the arm 12.

' should closely engage, and this space would diminish fromthe lower part of the jaw upwardly. In order to prevent this result, the

casing 28 has been inclined forwardly from the table, whereby as the piston 34 moves upwardly, as occasion may require, the jaw,

-while being moved upwardly, also moves forwardly at the same time thus kee )in it u i b in close contact with the rear end of the ma-- terial. In this way the material 'is held tightly in place against the gage bar, regardless of the upward movement of the jaw or its movement above the plane of the ta ,ble, since the devices are so constructed and arranged that the resultant of the upward and forward movement of the arm 38 and the retaining device thereon is to give the forward face of the jaw a vertical movement or a movement perpendicular to the table.

Vhilc I have hereindescribed one form in which I have worked out my invention for practical purposes, I do not desireto be limited to exact details of construction shown and described, since many changes in the details of construction and arrangement,

and combinationof parts, as set forth, will occur to aperson skilled in the art and are intended to fall within the purview of the claims appended hereto.
